重支持部材を備えなければならないことにある。Conventional forklift truck push/pull units come in several different types. One type is a standard push-and-pull fitting, such as that shown in Prudy U.S. Pat. There are fittings made by Anderson Clayton Company's Long Research Manufacturing Division. All of these have push-pull assemblies that include a frame, a push plate, and a push-pull linkage extending between the frame and the plate, consisting of a pantograph-type link capable of either horizontal or vertical rotation. Each of these devices also has a cross member at the bottom of its frame for removably attaching different types of special purpose load bearing members. Because they are attached to the frame bottom, the load bearing members, together with the push/pull assembly, are removable and laterally movable relative to the lift truck carriage. However, the cost of such standard push-pull units is relatively high. Part of the reason is that such units cannot use the standard forks of a lift truck to support the load, but rather have their own special load-bearing members that can be attached to the cross member at the bottom of the push-pull frame. It's something we have to prepare for.

No. 12, Farmer et al., U.S. Pat. No. 4,482,286
No. 4,619,579 to Frison. However, these designs do not allow the fork to be attached to or removed from the lift truck carriage along with the push/pull assembly. Also, the push-pull assembly and fork cannot be attached to the lift truck carriage without inserting a lateral displacement device between the carriage and the push-pull assembly, such as that shown in U.S. Pat. No. 3,460,700 to Clorava. They cannot move laterally together. This causes the push/pull assembly to protrude too far forward, reducing the load carrying capacity of the counterbalance lift truck on which the push/pull assembly is mounted.

引込みの制限を排除した。However, the mounting of the standard fork's tall uprights on the push-pull frame between the sides of the linkage limits the extent to which the horizontally pivoting link can be retracted, thus causing excessive protrusion of the push-pull assembly in its fully retracted position. , thus reducing the load-carrying stresses on the counterbalance track on which the unit is mounted. The unit ends up being the cascade 30C and 45C.
Canceled due to design. Although the above design does not allow the use of standard lift truck forks, it eliminates the retraction limitations of the push/pull assembly previously created by the upright portions of standard forks.

結する。The push-pull device 10 comprises an upright push-pull frame 22 which is attached to the upper fork mounting member 1 of the carriage.
It is detachably supported on the upward facing surface 16 of 2a. If it is not desired for the frame 22 to move laterally relative to the lift truck 12, the downwardly opening hooks 24 engage directly with the fork mounting members 12a. However, in the illustrated embodiment, the push-pull frame 22 can be moved laterally relative to the carriage 12. Therefore, unlike the conventional quick-mount type lateral movement bracket 26, a sliding bushing 28 is inserted between the fork mounting member 12a and the hook 24. Bushing 28 allows lateral sliding of hook 24, while bracket 26 provides a fixture for one end of hydraulic lateral displacement cylinder and piston assembly 32. The other end of the assembly is coupled to push/pull frame 22 for selectively moving the push/pull frame laterally relative to carriage 12 when actuated.

自在に掛合してこれらを垂直に支持することができる。The push-pull device is capable of using a standard load-bearing fork 18 of a lift truck as a load-bearing member of the push-pull device, and the fork 18 is removable, preferably by the lift truck carriage 12 in conjunction with the push-pull frame 22. To provide lateral movement, the push-pull frame 22 has an elevated transverse mounting member 56 with an upwardly directed lip-like surface 56 adjacent to the downwardly facing surface of the hook 24 and attached thereto. It is located in front thereof and laterally offset and outwardly relative to each pair of links 36 and 38. The mounting member 5G and its upward facing surface 58 are similar to the mounting member 12a of the carriage 12 and its upward facing surface 16 and can removably engage the hook 18a of the standard fork 18 to support them vertically.

いう従来の問題を克服することができる。This allows the rear links 36 and 38 to be substantially perpendicular to the upright portion 18b of the fork when the pusher plate is fully retracted, for example by the link 36, as shown in phantom in FIG. It becomes possible to extend. This minimizes the forward protrusion of the push-pull assembly in the fully retracted position, resulting in a reduction in load-carrying capacity that occurs in previous attempts to co-move a standard lift truck fork onto a push-pull frame. Conventional problems can be overcome.
